Consider that it's very much in Silk Road's interest that the regulations that currently create the transactional frictions on which it makes a profit remain as they are, or perhaps become even more restrictive. It's rent seeking in the same way that smuggling illegal immigrants is rent seeking. This does not require a broadened definition of rent seeking at all.

Smuggling illegal immigrants is not rent seeking. If an illegal-immigrant-smuggling company lobbied the government to tighten immigration controls, that would be rent seeking.
It's in the interests of the smugglers that tight immigration controls remain in place, just as it's in the interests of Silk Road that regulations on restricted substances remain in place.
They need not lobby directly for these restrictions, they have other organisations that will do that for them.
